On your drivers side seat do you have a seat cover, the problem is the seat cover pulls on the electric seat adjustment lever causing a cycling amperage draw with in the range you described. If you do not have a seat cover still check to see if the lever is jammed which still does happen without a seat cover.The other cause is a fault with the "Vehicle Electronics Module" which is technically called BEM "Body Electronic Module." Which fail very commonly, there is nothing to be nervous about, it is not a huge job but the BEM does require programming with the genuine diagnostic tool.http://www.justanswer.com/australia-car/33ian-battery-drains-night-bf-xr8-falcon-auto-elec.html Link to comment https://www.fordxr6turbo.com/forum/topic/87276-battery-drain-ba-xr6t/page/2/#findComment-1452400 Share on other sites More sharing options...

If ones out you have problems, limp mode in my case. They say it could be any one of the three,if its my BEM they can replace it with a second hand unit for $700 bucks Link to comment https://www.fordxr6turbo.com/forum/topic/87276-battery-drain-ba-xr6t/page/2/#findComment-1452431 Share on other sites More sharing options...

My Car: 2005 BA MK2 Turbo 6 Speed Manual. This is what I did: No Key in Ignition 1x Digital Multimeter set to measure Amps...Set to 10A Disconnected Neg. Battery Cable 1 Probe Wire to Battery -, 1Probe to Battery Cable... I used clips to hold them in place. Open and close Driver Door... Wait till interior lights go out to get 1st Meter reading. In my case it was 0.27 Amp. After waiting for 15 Minutes the reading changed to 0.08 Amp. All of that tells me that the my BEM is working. http://postimg.org/image/ndph6ib99/ Edited 29/01/14 06:13 AM by f-wolf 1 Link to comment https://www.fordxr6turbo.com/forum/topic/87276-battery-drain-ba-xr6t/page/2/#findComment-1452433 Share on other sites More sharing options...

Which is good I guess, it means the BEM is okay as I can start the car with this fuse pulled, its purely the ICC that it seems to fuse.New ICC needed?

You need to leave your meter hooked up for the hour to check if the drain stops.

Don't forget the PCM also has KAM (keep alive memory) that's a constant power feed to the pcm to (you guessed it) keep the memory alive.

So why don't you do a test like I did ??You never know what you will find out...
